BICYCLE.

SPECIFICATION forming part of Letters Patent No. 408,845, dated August13, 1889.

Application filed May 28, 1889. Serial No. 312,363. (No model.)

To all whom t may concern.: a socket o in one side, the relativelocations Be it known that I, CHARLES E. MCn of these parts being shownin Fig. 3. Inter- GLINOHEY, a citizen of the United States, reposedbetween the cam p and surface r of the siding at Chicago, in thecou'iity of Cook and housing A2 is a loose Wedge-block it, having 5State of Illinois, have invented a new and usea curved edge 'n' to fitthe surface i, a straight 5 5 ful Improvement in Bicycles, of which theedge n2 for the cam p to bear against, and a following is aspecification. socket n3 for one end of a helical spring m, My inventionrelates to an iinproveineiitin which extends at its opposite end intothe the propelling mechanism of bicycles, and is socket o', and is thusconfined between the io intended to be especially adapted for use withblock n and boss o. The hub A is loose upon 6o bicycles of the classwherein a large wheel is the shaft D; but the treadles E, sleeves F,followed by one of relatively small diameter. and shaft are firmlysecured together by keys The objects of my invention are, first, to Z Z,so that turning of the treadles iii the posiafford propelling mechanismof improved contive direction turns each disk F in the same 15 structionforbicycles, whereby the large wheel direction (indicated by arrows inFig. 3) and 6 5 may be revolved in the positive or forward causes thecain p to bear against the block n direction independently of thepedals, and, and wedge it against the surface fr of the hub, secondly,to afford, in connection with the runcausing the block th iis to engagethe said surning-gear of the large wheel of a bicycle of face andrevolve the wheel A. Y The opposite 2o the particular class abovedefined, mechanface of each disk F is recessed to afford an 7o ism forlessening the liability to the rider of inner peripheral surface 7c.what is technically denominated a headen G G are sleeves fitting snuglybut loosely In the drawings, Figure lis aview in broken over the sleevesF, and provided in each inelevatioii, mainly in dotted lines, of abicycle stance with a plate or disk G', which fits 2 5 provided with myimprovement with the against the shoulder q of the respective hous- 75crank and pedal removed; Fig. 2, a broken ing A2. Each disk G isprovided upon its longitudinal and mainly sectional viewof the face (seeFig: 4:) with. a bossi, affording a cani shaft, hub, and propellingmechanism involvi, anda prog ection t2, provided with a socket ing myinvention; and Figs. 3 and 4:, broken to receive one end o f a helicalspring 7i,which 3o andpartly-scctionalviews taken,respectively, pressesat its opposite end into a socket in a 8o on the lines 3 and 4 of Fig. 2and viewed in loose wedge-block g, which is interposed bethe directionof the arrows. 'tween the cani t" and surface 7c of the disk F, A is thefront wheel, B the front fork, and which surface surrounds the boss t'and block C the backbone of a bicycle. g, as shown. The outer edge g ofthe block 35 A is the hub of the front wheel, D the g conforms in shapeto the surface 7s, and the 85 shaft, andE E the pedal-cranks. The hub Ablock has a straight edgeg2 on its inner Side comprises'a sleeve fittingsnugly around the for the cam e to bear against. Upon its opaxle at t t,and which terminates at each end posite face each disk G carries asocket-piece in a housing A2, to which the spokes s of the H, rigidlysecured thereto by screws at, which,

4o wheel are secured. Each housing is turned for purposes of strength,extend through 9o out to produce an inner peripheral surface r the diskand b oss i. The sockets I-l are ar- -and shoulders q q', and isdesigned to receive ranged to receive the respective lower ends of partshereinafter described. the front fork B, which maybe secured therein F Fare sleeves fitting snugly around the by bolts y, as shown in Fig. l.This-construc- 45 shaftl), each carrying toward one end a plate tionrenders the front fork B, and canse- 95 or disk F which fits against theshoulder q quently the backbone C, substantially intein the housing A2.The face of each disk F gral with the sleeve G and its ,disk G. A isprovided with a central rigid projection or movement in the positivedirection of the disk boss p, having a cam-shaped edge p', affo'rd- Gand its boss t, which would be effected by 5o ing a cam, and a rigidstud or boss o, having the rise from the ground of the rear wheel Y ICOof the bicycle, would operate, by the pressure of the block g/ againstthe inner peri} iheral surface 7.1 of the disk li", to bind the disks(1" and F together. Movement of the wheel A in the positive directionotherwise than by means of force applied to the pedals will not producethe gripping together of the parts F' and A, so that the pedals, shaft,sleeve F, and its disk F would `remain unaffected. In like mannermovement of the pedals in the positivedirection,which rotates the wheelA,pro duees no gripping effect between the parts 'F F and G 1l Themechanism described is all fitted together with exaetness, so that thegripping effect produced of the parts maybe practically instantaneous orwithout appreciable lost motion of the parts primarily moved. The officeof the springs m 7i is to maintain the blocks n and y, respectively, inposition to perform their functions with the least possible turningagainst them of the adjacent cams, and the springs are sufficientlyelastic to prevent their pressure against the blocks from producing anyappreciable binding effect of the latter against the rclatively-adjaeentinner peripheral surfaces when the cams are not in the condition ofbearing against the wedge-blocks.

The effect of the above construction in the use of the bicycle is that,after motion of the wheel A is produced by means of the pedals the ridermay rest himself by stopping the motion of the pedals and helding hisfeet against them, while the inertia of the wheel A will carry it aheadsome distance, and in traveling down an inclined surface the pedals mayalways remain at rest, if desired, and serve to support the feet of therider. As any sudden movement of the backbone in an upward directioncauses the disk G to bind directly against the disk F', it would havethe effect of jarring the pedal which may happen to be in rearof theother, and therefore rising if the pedals are being operated against thesole of the riders foot, so that further rising of the backbone and rearwheel would be against the force which the weight of the rider wouldexert upon the pedal; and should the obstruction which the large wheelstrikes be one that would tend to stop its forward movement the grippingof the backbone against the shaft would tend io give, momentarily, a newimpetus to the wheel, and thus aid in sending it over the obstruction.

The mechanism described, while it operates under all circumstances tolessen the danger of accident, is rendered especiallyY elfeetive whenthe pedals are at rest, as they may be when traveling down an inclinedplane, and when the rider should keep the rear pedal at an an gle whichwould offer the greatestleverage for his weight to operate with shouldthe front wheel strike an obstruction which would tend to lift the rearwheel and produce a header.

While I design. myimprevement espeei ally for use on bicycles, thegripping mechanism, which is shown as engaging directly with the hub,may be used for the same general purpose as that described in connectionwith wheels other than the wheels of bicycles, and it may, obviously, beemployed in a bicycle independently of the gripping mechanism forpreventing rise (or material rise) of the backbone.

rlhe propelling mechanism maybe provided at one end of the shaft D only,though it is preferably provided at each end, as shown and described.

filati claim as new, and desire to secure by Letters Patent, is
